--- Comment #8 from Patrick Rudolph <patrick.rudolph@br-automation.com> ---
I could reproduce the issue:
Moving the mouse over plasmashell's tray icons or startmenu entries causes the
memory in ksmserver to rise.

By looking at plasmashell's output I found thousands of "_xgeWireToEvent:
Unknown extension 148, this should never happen.".

By redirecting plasmashell's output to /dev/null the issue no longer occurs.

It looks like ksmserver doesn't read/discard the spawned child's output, but
collects them in some internal buffer.

The hotfix for me is to install libXext 1.3.3. But it just covers the bug, as
other applications could spam a lot and cause a memory bloat in ksmserver.
